Thomas: Thank you again for your excellent reply.
1. I was posting to the email list at http://www.mail-archive.com/cdwrite@other.debian.org/info.html. I thought that was the gateway to cdwrite messages. It substitutes the [EMAIL PROTECTED] portion of the subject and message with EMAIL PROTECTED]. This isn't so bad when the sender (me in this case) wants to protect his email address from spam harvesters, but it does make it difficult to get the details of the reported message. Your suggested email list address http://lists.debian.org/cdwrite/2007/07/threads.html is what I'm using now, and I can see all the text, including my return email address. Oh, well. 2. I came to growisofs because it was suggested to me that this would be able to restore the DVD+RW media to its virgin state. Evidently that is not possible, which seems very strange to me at the least. You can do it with DVD-RW and virtually every other recordable media I am aware of. 3. The reason I want to do it is because I've been having problems with the "erased" media format that leaves a Session 1 - track 01 structure on the disc, length 4.7 sales GB, closed, but with nulls in all the track sectors. Some software (e.g. Plextools) gets very confused by this situation, and becomes virtually useless unless it has something to work on. So in cases like this you always want to be able to return to a known good state -- in this case, blank media. Everything understands that. 4. You mention some reformatting with DVD-RW (not DVD+RW). I got a -RW disc here, and was able with simple erase to recover what Isobuster and others recognize as a simple Blank DVD-RW. So for my purposed the intermediate operations you suggest are not necessary in the instant case, though might be in some other context. 5. I sent an email to Andy Polyakov, asking him where to report this bug. I didn't realize he was the author of growisofs. Maybe he'll look into doing a true blanking of the media. I mean, how hard can it be to simply zap the specific sectors that hold this bogus session - track 01 structure? Thanks for your help -- greatly appreciated. -- Roy Zider 2. -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of "unsubscribe". Trouble? Contact [EMAIL PROTECTED]
